Groundwater Flow Modeling - Idaho National Laboratory
Numerical models are being used to better understand the flow of groundwater and the transport of radiochemical and chemical constituents in the eastern Snake River Plain aquifer system.
The models, developed at the INL, afford scientists a framework to organize their knowledge and concepts of groundwater systems and to provide insights for water-resource managers for future water...
Geochemical Modeling - Idaho National Laboratory
Geochemical models for the eastern Snake River Plain aquifer system are being used to better understand the flow of groundwater beneath the INL and, ultimately, to better understand the fate and transport of radiochemical and chemical constituents. As water moves through the ground, it picks up chemicals from the gases and rocks it comes in contact with.
Developing Geological Framework - Idaho National Laboratory
As basaltic lava cools and hardens, the inclination, declination, and polarity of the Earth’s ambient magnetic field is recorded in the magnetic minerals of the rock. The recorded magnetic values are largely preserved and can be deciphered by paleomagnetic analysis.
Drilling and Coring - Idaho National Laboratory
We drill and maintain wells around the INL to monitor and sample groundwater, obtain basalt and sediment cores for study and analysis, and study the physical properties of the subsurface (geophysical logging).
This information helps us to improve the scientific understanding of the eastern Snake River Plain and its aquifer. In particular, we are examining the subsidence of the plain and...
The USGS collects, analyzes, and distributes data on a wide variety of water-related issues and resources. Much of our data is publicly available through the National Water Information System (NWIS), but additional datasets and analytical tools are also available.
